[RPi] Sidplay decoder simply refuses to work

emmanu888 · March 9, 2025 at 12:34 AM

Kodi keeps throwing up errors about the addon being unable to load and i refuse to believe i'm the only one trying to play SID tunes on a Raspberry Pi through Kodi.

It just says an unknown error has occurred, surely this should be fixed by now but even older versions won't work. The oldest version will even crash the Pi when trying to play a SID tune.

It's so much more helpful when you post a log file with the actual error. You need to report it in Kodi forums to the add-on maintainers.

The undefined symbol: _ZTI7SidTune unfortunately is a LE linking error.

Pushed a PR

Merged. The updated add-on should be in the repo in the next 24-36 hours.

I tried LE 12.0.2 on RPI3 with manually installing sidplay-addon 21.0.2.2 for armV7 from zip-file found on addons.libreelec.tv
With this version the SID files are shown, but when selecting a file to be played, LE reboots.

a) Installing from LibreELEC repo for Ganeric-legacy LE12 works for me

b) A reboot is unlikely, usually kodi is crashing and restarted. In this case a crashlog is generated. Reboot, reproduce the crash and upload crash log via LE Settings Addon or pastecrash

technics · May 25, 2025 at 11:40 AM

Yes, it's crashing, not rebooting.
Please see attached crash-log.

When selecting LibreElec-Repo (v12.0.0, although LE is v12.0.2) I can only choose to install version 20.2.0.7, but this version is not working at all.
So, I installed newer version 21.0.2.2 from zip, which should include the fix.

**mglae** · May 25, 2025 at 4:30 PM

Please enable debug logging (again), reboot and post the complete log including system log as requested in post #6

For the repo issue force a manual update via addon options.

technics · May 25, 2025 at 6:12 PM

Here you go: crashlog

I cannot update the repo - it just says, no other version available...

**Da Flex** · May 25, 2025 at 9:08 PM

Quote from technics

Here you go: crashlog

I guess it crashes due to an unknown audio codec:

But even debug logging does not show which python code was called.

I'm unsure what to recommend. Maybe testing a fresh install on a spare SD card.

technics · May 26, 2025 at 7:48 PM

OK, I just did a fresh installation of LE12.0.2 and only installed sidplay 21.0.2 from repo (now I could select this version directly).
Result is the same - when selecting a SID-file, LE crashes.
Here is the log from pastecrash

**Da Flex** · May 26, 2025 at 10:00 PM

technics Most add-on developers are at Kodi forum. I suggest to ask over there.

technics · May 27, 2025 at 8:10 AM

I just found this issue also reported in github of sidplay

mglae : Maybe you could take a look at this?

**mglae** · May 27, 2025 at 3:41 PM

This is fixed, see post #3 of this thread.

For further testing you can update your fresh install first to current LE12 nightly and them to LE13 nightly. Both are available from https://test.libreelec.tv, check the date to get the most recent ones.

technics · May 27, 2025 at 4:00 PM

OK, done - using latest LE12 nightly (LibreELEC-RPi2.arm-12.0-nightly-20250416-e25b5e0) causes crash
Using latest LE13 nightly (LibreELEC-RPi2.arm-13.0-nightly-20250525-8f9cee7) is working - this is the log!
Sorry, I forgot to enable debug-logging... if this is still of interest, I could enable debug and repeat testing again.

Thank you for looking into this.
Would it be possible to also get it fixed for LE12?

**mglae** · May 28, 2025 at 2:50 PM

As long the reason is not known there is nothing that can be done. If SID files are important use LE13 as a work around.
